Charlie Rose’s respected journalism career came crashing down Tuesday after three broadcast companies abruptly cut ties with him over sexual harassment allegations, and his CBS co-hosts reprimanded him live on the air.

CBS News President David Rhodes told staff in an email that Rose was let go over the “extremely disturbing and intolerable behavior” reported by employees of the interview show Rose did for PBS,

“Despite Charlie’s important journalistic contribution to our news division, there is absolutely nothing more important, in this or any organization, than ensuring a safe, professional workplace — a supportive environment where people feel they can do their best work,” Rhodes said in the memo.

“I’ve often heard that things used to be different,” he continued. “And no one may be able to correct the past. But what may once have been accepted should not ever have been acceptable.”
